The term "car" is commonly used by itself in American English when a rail context is implicit. Indian English sometimes uses "bogie" in the same manner,[1] though the term has other meanings in other variants of English. In American English, "railcar" is a generic term for a railway vehicle; in other countries "railcar" refers specifically to a self-propelled, powered, railway vehicle.

Although some cars exist for the railroad's own use – for track maintenance purposes, for example – most carry a revenue-earning load of passengers or freight, and may be classified accordingly as passenger cars or coaches on the one hand or freight cars (or wagons) on the other.

In standard-gauge cars, seating is usually configured into ranges of between three and five seats across the width of the car, with an aisle in between (resulting in arrangements of 2+1, 2+2 or 3+2 seats) or at the side. Tables may be provided between seats facing one another. Alternatively, seats facing in the same direction may have access to a fold-down ledge on the back of the seat in front.

If the aisle is located between seats, seat rows may face the same direction, or be grouped, with twin rows facing each other.

In some vehicles intended for commuter services, seats are positioned with their backs to the side walls, either on one side or more commonly on both, facing each other across the aisle. This gives a wide accessway and allows room for standing passengers at peak times, as well as improving loading and unloading speeds.

If the aisle is at the side, the car is usually divided into small compartments. These usually contain six seats, although sometimes in second class they contain eight, and sometimes in first class they contain four.

Passenger cars can take the electricity supply for heating and lighting equipment from either of two main sources: directly from a head end power generator on the locomotive via bus cables, or by an axle-powered generator which continuously charges batteries whenever the train is in motion.

Modern cars usually have either air-conditioning or windows that can be opened (sometimes, for safety, not so far that one can hang out), or sometimes both. Various types of onboard train toilet facilities may also be provided.

Other types of passenger car exist, especially for long journeys, such as the dining car, parlor car, disco car, and in rare cases theater and movie theater car. In some cases another type of car is temporarily converted to one of these for an event.

Observation cars were built for the rear of many famous trains to allow the passengers to view the scenery. These proved popular, leading to the development of dome cars multiple units of which could be placed mid-train, and featured a glass-enclosed upper level extending above the normal roof to provide passengers with a better view.

Sleeping cars outfitted with (generally) small bedrooms allow passengers to sleep through their night-time trips, while couchette cars provide more basic sleeping accommodation. Long-distance trains often require baggage cars for the passengers' luggage. In European practice it used to be common for day coaches to be formed of compartments seating 6 or 8 passengers, with access from a side corridor. In the UK, Corridor coaches fell into disfavor in the 1960s and 1970s partially because open coaches are considered more secure by women traveling alone.[citation needed]

A "trainset" (or "set") is a semi-permanently arranged formation of cars, rather than one created "ad hoc" out of whatever cars are available. These are only broken up and reshuffled 'on shed' (in the maintenance depot). Trains are then built of one or more of these 'sets' coupled together as needed for the capacity of that train.

Often, but not always, passenger cars in a train are linked together with enclosed, flexible gangway connections through which passengers and crewmen can walk. Some designs incorporate semi-permanent connections between cars and may have a full-width connection, effectively making them one long, articulated 'car'. In North America, passenger cars also employ tightlock couplings to keep a train together in the event of a derailment or other accident.

Many multiple unit trains consist of cars which are semi-permanently coupled into sets: these sets may be joined together to form larger trains, but generally passengers can only move around between cars within a set. This "closed" arrangement keeps parties of travellers and their luggage together, and hence allows the separate sets to be easily split to go separate ways. Some multiple-unit trainsets are designed so that corridor connections can be easily opened between coupled sets; this generally requires driving cabs either set to the side or (as in the Dutch Koploper or the Japanese 285 series) above the passenger compartment. These cabs or driving trailers are also useful for quickly reversing the train.

Freight cars (US), goods wagons (UIC), or trucks (UK) exist in a wide variety of types, adapted to carry a host of goods. Originally there were very few types of cars; the flat car or wagon, and the boxcar (US/Canada), covered wagon (UIC) or van (UK), were among the first. Freight cars or goods wagons are generally categorized as follows:

Open wagon (UIC): railway wagon with an open top but enclosed sides and ends, for bulk commodities and other goods that might slide off.

Hoppers: similar to gondolas but with bottom dump doors for easy unloading of things like coal, ore, grain, cement, ballast and the like. Short hoppers for carrying iron ore are called ore jennys in the US.

Lorry (US/Canada): An open wagon (UIC) or gondola (US/Canada) with a tipping trough, often found in mines. See also Tippler.

The first two main-line all aluminum passenger cars were exhibited at the 1933-35 Chicago World's Fair by Pullman Company.[3] Aluminum freighcars have a higher net-to-tare ratio of 4.9 than traditional steel based wagons, which have 3.65.[4]

Train-based ICBMs do offer some advantages over missiles in fixed silos, namely that the enemy can never be sure where they are—or, more accurately, where all of them are at any given moment. But as a 2014 RAND study[9] pointed out, rail and truck launchers have their drawbacks. Maintaining a missile on a train is more difficult than in a silo, while rail lines and roads can be blocked by snow, which tends to restrict railroad ICBMs to warmer climates. In addition, because there are only a limited number of rail lines and highways in an area, enemy surveillance can focus on a few areas. And, once located, mobile missiles are more vulnerable than ICBMs in hardened silos.[10]

Rail transport
–
Rail transport is a means of conveyance of passengers and goods on wheeled vehicles running on rails, also known as tracks. It is also referred to as train transport. In contrast to road transport, where vehicles run on a flat surface. Tracks usually consist of rails, installed on ties and ballast, on which the rolling stock, usually fitted with metal wheels. Other variations are possible, such as slab track, where the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a transport system generally encounters lower frictional resistance than road vehicles, so passenger. The operation is carried out by a company, providing transport between train stations or freight customer facilities. Power is provided by locomotives which either draw electric power from a railway system or produce their own power. Most tracks are accompanied by a signalling system, Railways are a safe land transport system when compared to other forms of transport. The oldest, man-hauled railways date back to the 6th century BC, with Periander, one of the Seven Sages of Greece, Rail transport blossomed after the British development of the steam locomotive as a viable source of power in the 19th centuries. With steam engines, one could construct mainline railways, which were a key component of the Industrial Revolution, also, railways reduced the costs of shipping, and allowed for fewer lost goods, compared with water transport, which faced occasional sinking of ships. The change from canals to railways allowed for markets in which prices varied very little from city to city. In the 1880s, electrified trains were introduced, and also the first tramways, starting during the 1940s, the non-electrified railways in most countries had their steam locomotives replaced by diesel-electric locomotives, with the process being almost complete by 2000. During the 1960s, electrified high-speed railway systems were introduced in Japan, other forms of guided ground transport outside the traditional railway definitions, such as monorail or maglev, have been tried but have seen limited use. The history of the growth, decline and restoration to use of transport can be divided up into several discrete periods defined by the principal means of motive power used. The earliest evidence of a railway was a 6-kilometre Diolkos wagonway, trucks pushed by slaves ran in grooves in limestone, which provided the track element. The Diolkos operated for over 600 years, Railways began reappearing in Europe after the Dark Ages. The earliest known record of a railway in Europe from this period is a window in the Minster of Freiburg im Breisgau in Germany

Rail transport operations
–
A railway has two major components, the rolling stock and the infrastructure. The operation of the railway is through a system of control, originally by mechanical means, signalling systems used to control the movement of traffic may be either of fixed block or moving block variety. Fixed block signalling Most blocks are fixed blocks, i. e. they delineate a section of track between two defined points, on timetable, train order, and token-based systems, blocks usually start and end at selected stations. On signalling-based systems, blocks start and end at signals. Alternatively, cab signalling may be in use, the lengths of blocks are designed to allow trains to operate as frequently as necessary. A lightly used line might have blocks many kilometres long. Moving block signalling A disadvantage of fixed blocks is that the trains are permitted to run, the longer the stopping distance. With moving block, computers are used to calculate a safe zone, behind each moving train, the system depends on precise knowledge of where each train is and how fast it is moving. With moving block, lineside signals are not provided, and instructions are passed direct to the trains and it has the advantage of increasing track capacity by allowing trains to run much closer together. Most rail systems serve a number of functions on the track, carrying local, long distance and commuter passenger trains. The emphasis on each varies by country, some urban rail transit, rapid transit and light rail systems are isolated from the national system in the cities they serve. Some freight lines serving mines are also isolated, and these are owned by the mine company. An industrial railway is a rail system used inside factories or mines. Steep grade railways are isolated, with special safety systems. The permanent way trails through the physical geography, the tracks geometry is limited by the physical geography. Trains are pushed/pulled by one or more locomotive units, two or more locomotives coupled in multiple traction are frequently used in freight trains. Railroad cars or rolling stock consist of cars, freight cars, maintenance cars. Modern passenger trains sometimes are pushed/pulled by a tail and head unit, many passenger trains consist of multiple units with motors mounted beneath the passenger cars

3.
Track (rail transport)
–
The track on a railway or railroad, also known as the permanent way, is the structure consisting of the rails, fasteners, railroad ties and ballast, plus the underlying subgrade. It enables trains to move by providing a surface for their wheels to roll upon. For clarity it is referred to as railway track or railroad track. Tracks where electric trains or electric trams run are equipped with a system such as an overhead electrical power line or an additional electrified rail. The term permanent way also refers to the track in addition to structures such as fences etc. Most railroads with heavy traffic use continuously welded rails supported by sleepers attached via baseplates that spread the load, a plastic or rubber pad is usually placed between the rail and the tieplate where concrete sleepers are used. The rail is held down to the sleeper with resilient fastenings. For much of the 20th century, rail track used softwood timber sleepers and jointed rails, jointed rails were used at first because contemporary technology did not offer any alternative. The joints also needed to be lubricated, and wear at the mating surfaces needed to be rectified by shimming. For this reason jointed track is not financially appropriate for heavily operated railroads, timber sleepers are of many available timbers, and are often treated with creosote, copper-chrome-arsenic, or other wood preservative. Pre-stressed concrete sleepers are used where timber is scarce and where tonnage or speeds are high. Steel is used in some applications, the track ballast is customarily crushed stone, and the purpose of this is to support the sleepers and allow some adjustment of their position, while allowing free drainage. A disadvantage of traditional track structures is the demand for maintenance, particularly surfacing and lining to restore the desired track geometry. Weakness of the subgrade and drainage deficiencies also lead to maintenance costs. This can be overcome by using ballastless track, in its simplest form this consists of a continuous slab of concrete with the rails supported directly on its upper surface. There are a number of systems, and variations include a continuous reinforced concrete slab. Many permutations of design have been put forward, however, ballastless track has a high initial cost, and in the case of existing railroads the upgrade to such requires closure of the route for a long period. Its whole-life cost can be lower because of the reduction in maintenance, some rubber-tyred metros use ballastless tracks

4.
High-speed rail
–
High-speed rail is a type of rail transport that operates significantly faster than traditional rail traffic, using an integrated system of specialized rolling stock and dedicated tracks. The first such system began operations in Japan in 1964 and was known as the bullet train. High-speed trains normally operate on standard gauge tracks of continuously welded rail on grade-separated right-of-way that incorporates a large turning radius in its design, only in Europe does HSR cross international borders. China has 22,000 kilometres of HSR as of end December 2016, while high-speed rail is most often designed for passenger travel, some high-speed systems also offer freight service. Multiple definitions for high-speed rail are in use worldwide, the European Union Directive 96/48/EC, Annex 1 defines high-speed rail in terms of, Infrastructure, track built specially for high-speed travel or specially upgraded for high-speed travel. Minimum Speed Limit, Minimum speed of 250 km/h on lines built for high speed. This must apply to at least one section of the line, Rolling stock must be able to reach a speed of at least 200 km/h to be considered high speed. Operating conditions, Rolling stock must be designed alongside its infrastructure for complete compatibility, safety and quality of service, category II – Existing tracks specially upgraded for high speeds, allowing a maximum running speed of at least 200 km/h. Category III – Existing tracks specially upgraded for high speeds, allowing a maximum running speed of at least 200 km/h, the UIC prefers to use definitions because they consider that there is no single standard definition of high-speed rail, nor even standard usage of the terms. They make use of the European EC Directive 96/48, stating that high speed is a combination of all the elements which constitute the system, infrastructure, rolling stock and operating conditions. The International Union of Railways states that high-speed rail is a set of unique features, many conventionally hauled trains are able to reach 200 km/h in commercial service but are not considered to be high-speed trains. These include the French SNCF Intercités and German DB IC, National domestic standards may vary from the international ones. Railways were the first form of land transportation and had an effective monopoly on passenger traffic until the development of the motor car. Speed had always been an important factor for railroads and they tried to achieve higher speeds. The line used three-phase current at 10 kilovolts and 45 Hz, on 23 October 1903, the S&H-equipped railcar achieved a speed of 206.7 km/h and on 27 October the AEG-equipped railcar achieved 210.2 km/h. These trains demonstrated the feasibility of electric high-speed rail, however, after the breakthrough of electric railroads, it was clearly the infrastructure – especially the cost of it – which hampered the introduction of high-speed rail. Several disasters happened – derailments, head-on collisions on single-track lines, collisions with traffic at grade crossings. The physical laws were well-known, i. e. if the speed was doubled, the radius should be quadrupled

5.
Track gauge
–
In rail transport, track gauge is the spacing of the rails on a railway track and is measured between the inner faces of the load-bearing rails. All vehicles on a network must have running gear that is compatible with the track gauge, as the dominant parameter determining interoperability, it is still frequently used as a descriptor of a route or network. There is a distinction between the gauge and actual gauge at some locality, due to divergence of track components from the nominal. Railway engineers use a device, like a caliper, to measure the actual gauge, the nominal track gauge is the distance between the inner faces of the rails. In current practice, it is specified at a distance below the rail head as the inner faces of the rail head are not necessarily vertical. In some cases in the earliest days of railways, the company saw itself as an infrastructure provider only. Colloquially the wagons might be referred to as four-foot gauge wagons, say and this nominal value does not equate to the flange spacing, as some freedom is allowed for. An infrastructure manager might specify new or replacement track components at a variation from the nominal gauge for pragmatic reasons. Track is defined in old Imperial units or in universally accepted metric units or SI units, Imperial units were established in United Kingdom by The Weights and Measures Act of 1824. In addition, there are constraints, such as the load-carrying capacity of axles. Narrow gauge railways usually cost less to build because they are lighter in construction, using smaller cars and locomotives, as well as smaller bridges, smaller tunnels. Narrow gauge is often used in mountainous terrain, where the savings in civil engineering work can be substantial. Broader gauge railways are generally expensive to build and require wider curves. There is no single perfect gauge, because different environments and economic considerations come into play, a narrow gauge is superior if ones main considerations are economy and tight curvature. For direct, unimpeded routes with high traffic, a broad gauge may be preferable, the Standard, Russian, and 46 gauges are designed to strike a reasonable balance between these factors. In addition to the general trade-off, another important factor is standardization, once a standard has been chosen, and equipment, infrastructure, and training calibrated to that standard, conversion becomes difficult and expensive. This also makes it easier to adopt an existing standard than to invent a new one and this is true of many technologies, including railroad gauges. The reduced cost, greater efficiency, and greater economic opportunity offered by the use of a common standard explains why a number of gauges predominate worldwide

6.
Train station
–
A train station, railway station, railroad station, or depot is a railway facility where trains regularly stop to load or unload passengers or freight. It generally consists of at least one platform and a station building providing such ancillary services as ticket sales. If a station is on a line, it often has a passing loop to facilitate traffic movements. The smallest stations are most often referred to as stops or, in parts of the world. Stations may be at level, underground, or elevated. Connections may be available to intersecting rail lines or other modes such as buses. In British usage, the station is commonly understood to mean a railway station unless otherwise qualified. In the United States, the most common term in contemporary usage is train station, Railway station and railroad station are less frequent. Outside North America, a depot is place where buses, trains, or other vehicles are housed and maintained and from which they are dispatched for service. The two-storey Mount Clare station in Baltimore, Maryland, which survives as a museum, first saw service as the terminus of the horse-drawn Baltimore. The oldest terminal station in the world was Crown Street railway station in Liverpool, built in 1830, as the first train on the Liverpool-Manchester line left Liverpool, the station is slightly older than the Manchester terminal at Liverpool Road. The station was the first to incorporate a train shed, the station was demolished in 1836 as the Liverpool terminal station moved to Lime Street railway station. Crown Street station was converted to a goods station terminal, the first stations had little in the way of buildings or amenities. The first stations in the modern sense were on the Liverpool and Manchester Railway, manchesters Liverpool Road Station, the second oldest terminal station in the world, is preserved as part of the Museum of Science and Industry in Manchester. It resembles a row of Georgian houses, dual-purpose stations can sometimes still be found today, though in many cases goods facilities are restricted to major stations. In rural and remote communities across Canada and the United States, such stations were known as flag stops or flag stations. Many stations date from the 19th century and reflect the architecture of the time. Countries where railways arrived later may still have such architecture, as later stations often imitated 19th-century styles, various forms of architecture have been used in the construction of stations, from those boasting grand, intricate, Baroque- or Gothic-style edifices, to plainer utilitarian or modernist styles

Train
–
A train is a form of rail transport consisting of a series of vehicles that usually runs along a rail track to transport cargo or passengers. Motive power is provided by a locomotive or individual motors in self-propelled multiple units. Although historically steam propulsion dominated, the most common forms are diesel and electric locomotives. Other energy sources include horses, engine or water-driven rope or wire winch, gravity, pneumatics, batteries, the word train comes from the Old French trahiner, from the Latin trahere pull, draw. There are various types of trains that are designed for particular purposes, a train may consist of a combination of one or more locomotives and attached railroad cars, or a self-propelled multiple unit. The first trains were rope-hauled, gravity powered or pulled by horses, from the early 19th century almost all were powered by steam locomotives. A passenger train is one which includes passenger-carrying vehicles which can often be very long, one notable and growing long-distance train category is high-speed rail. In order to much faster operation over 500 km/h, innovative Maglev technology has been researched for years. In most countries, such as the United Kingdom, the distinction between a tramway and a railway is precise and defined in law, a freight train uses freight cars to transport goods or materials. Freight and passengers may be carried in the train in a mixed consist. Rail cars and machinery used for maintenance and repair of tracks, etc. are termed maintenance of way equipment, similarly, dedicated trains may be used to provide support services to stations along a train line, such as garbage or revenue collection. There are various types of trains that are designed for particular purposes, a train can consist of a combination of one or more locomotives and attached railroad cars, or a self-propelled multiple unit. Trains can also be hauled by horses, pulled by a cable, special kinds of trains running on corresponding special railways are atmospheric railways, monorails, high-speed railways, maglev, rubber-tired underground, funicular and cog railways. A passenger train may consist of one or several locomotives and coaches, alternatively, a train may consist entirely of passenger carrying coaches, some or all of which are powered as a multiple unit. In many parts of the world, particularly the Far East and Europe, freight trains are composed of wagons or trucks rather than carriages, though some parcel and mail trains are outwardly more like passenger trains. Trains can also be mixed, comprising both passenger accommodation and freight vehicles, special trains are also used for track maintenance, in some places, this is called maintenance of way. A train with a locomotive attached at each end is described as top and tailed, where a second locomotive is attached temporarily to assist a train up steep banks or grades it is referred to as banking in the UK, or helper service in North America. Recently, many loaded trains in the United States have been made up one or more locomotives in the middle or at the rear of the train

8.
Locomotive
–
A locomotive or engine is a rail transport vehicle that provides the motive power for a train. A locomotive has no payload capacity of its own, and its purpose is to move the train along the tracks. In contrast, some trains have self-propelled payload-carrying vehicles and these are not normally considered locomotives, and may be referred to as multiple units, motor coaches or railcars. The use of these vehicles is increasingly common for passenger trains. Traditionally, locomotives pulled trains from the front, however, push-pull operation has become common, where the train may have a locomotive at the front, at the rear, or at each end. Prior to locomotives, the force for railroads had been generated by various lower-technology methods such as human power, horse power. The first successful locomotives were built by Cornish inventor Richard Trevithick, in 1804 his unnamed steam locomotive hauled a train along the tramway of the Penydarren ironworks, near Merthyr Tydfil in Wales. Although the locomotive hauled a train of 10 long tons of iron and 70 passengers in five wagons over nine miles, the locomotive only ran three trips before it was abandoned. Trevithick built a series of locomotives after the Penydarren experiment, including one which ran at a colliery in Tyneside in northern England, the first commercially successful steam locomotive was Matthew Murrays rack locomotive, Salamanca, built for the narrow gauge Middleton Railway in 1812. This was followed in 1813 by the Puffing Billy built by Christopher Blackett and William Hedley for the Wylam Colliery Railway, Puffing Billy is now on display in the Science Museum in London, the oldest locomotive in existence. In 1814 George Stephenson, inspired by the locomotives of Trevithick. He built the Blücher, one of the first successful flanged-wheel adhesion locomotives, Stephenson played a pivotal role in the development and widespread adoption of steam locomotives. His designs improved on the work of the pioneers, in 1825 he built the Locomotion for the Stockton and Darlington Railway, north east England, which became the first public steam railway. In 1829 he built The Rocket which was entered in and won the Rainhill Trials and this success led to Stephenson establishing his company as the pre-eminent builder of steam locomotives used on railways in the United Kingdom, the United States and much of Europe. The first inter city passenger railway, Liverpool and Manchester Railway, opened in 1830, there are a few basic reasons to isolate locomotive train power, as compared to self-propelled vehicles. Maximum utilization of power cars Separate locomotives facilitate movement of costly motive power assets as needed, flexibility Large locomotives can substitute for small locomotives when more power is required, for example, where grades are steeper. As needed, a locomotive can be used for freight duties. Obsolescence cycles Separating motive power from payload-hauling cars enables replacement without affecting the other, to illustrate, locomotives might become obsolete when their associated cars did not, and vice versa

History of rail transport
–
Including systems with man or horse power, and tracks or guides made of stone or wood, the history of rail transport dates back as far as the ancient Greeks. Wagonways were relatively common in Europe from about 1500 through 1800, mechanised rail transport systems first appeared in England in the 1820s. These systems, which use of the steam locomotive, were critical to the Industrial Revolution. They have remained the form of long distance land transportation for many bulk materials such as coal, ore, grains, stone and sand. Reduction in friction was one of the reasons for the success of railroads compared to wagons. This was demonstrated on an iron plate-covered wooden tramway in 1805 at Croydon in England, “A good horse on an ordinary turnpike road can draw two thousand pounds, or one ton. A party of gentlemen were invited to look upon the experiment, twelve wagons were loaded with stones, till each wagon weighed three tons, and the wagons were fastened together. A horse was then attached, which drew the wagons with ease, six miles in two hours, having stopped four times, in order to show he had the power of starting, as well as drawing his great load. ”Wheeled vehicles pulled by men and animals ran in grooves in limestone, which provided the track element, preventing the wagons from leaving the intended route. The Diolkos was in use for over 650 years, until at least the 1st century AD, the first horse-drawn wagonways also appeared in ancient Greece, with others to be found on Malta and various parts of the Roman Empire, using cut-stone tracks. They fell into disuse as the Roman Empire collapsed, in 1515, Cardinal Matthäus Lang wrote a description of the Reisszug, a funicular railway at the Hohensalzburg Castle in Austria. The line originally used wooden rails and a hemp haulage rope, the line still exists, albeit in updated form, and is possibly the oldest wagonway still to operate. Wagonways are thought to have developed in Germany in the 1550s to facilitate the transport of ore tubs to and from mines, such an operation was illustrated in 1556 by Georgius Agricola. This used Hund carts with unflanged wheels running on wooden planks, such a transport system was used by German miners at Caldbeck, Cumbria, England, perhaps from the 1560s. An alternative explanation derives it from the Magyar hintó - a carriage, there are possible references to their use in central Europe in the 15th century. The first true railway is now suggested to have been a railway made at Broseley in Shropshire. This carried coal for James Clifford from his mines down to the river Severn to be loaded onto barges, though the first documentary record of this is later, its construction probably preceded the Wollaton Wagonway, completed in 1604, hitherto regarded as the earliest British installation. This ran from Strelley to Wollaton near Nottingham, another early wagonway is noted onwards. Huntingdon Beaumont, who was concerned with mining at Strelley, also laid down broad wooden rails near Newcastle upon Tyne, by the 18th century, such wagonways and tramways existed in a number of areas

Glossary of rail transport terms
–
Rail terminology is a form of technical terminology. The difference between the American term railroad and the term railway is the most significant difference in rail terminology. There are also others, due to the development of rail transport systems in different parts of the world. Various global terms are presented here, where a term has multiple names, the abbreviation UIC refers to standard terms adopted by the International Union of Railways in its official publications and thesaurus. Instead, an alarm is sounded at an interval in which the operator must respond by pressing a button to reset the alarm. If the operator does not respond within a time, the prime mover is automatically throttled back to idle. They also serve to support the arch or equivalent. The only significant difference is the size, measured in feet rather than inches, the fireman remains with the locomotive and, when the driver is at the other end, the fireman controls the cut off and vacuum ejectors in addition to his usual duties. Axlebox or axle box The housing that holds the bearings of a locomotive The housing attaching the end of the axle to the bogie which contains the bearing allowing the axle to rotate. Bad order A tag or note applied to a piece of equipment. Generally, equipment tagged as bad order is not to be used until repairs are performed, revolving masses can easily be balanced by counterweights, but the balancing of reciprocating parts is a matter of compromise and judgement. Balloon A looped length of track, usually at the end of a spur or branch, can be used as part of a freight installation to allow the loading or unloading of bulk materials without the need to stop the train. Early locomotives burned coke, provision of an arch was necessary before coal could be used without producing excessive smoke. Many early railroads were broad gauge, for example the Great Western Railway in the UK which adopted 7 ft gauge until it was converted to standard gauge in the 1860s - 1890s, russia still has over 80,000 km of broad gauge railroads. Broad gauge is also normal in Spain and Portugal, in India, as well as Ireland, cabless A locomotive without a cab. Commonly referred to as a B unit or a Slug, although not all Slugs are cabless, caboose A railroad car attached usually to the end of a train, in which railroad workers could ride and monitor track and rolling stock conditions. Largely obsolete, having been replaced by the electronic end-of-train device, the correct classification is CoCo, but Co-Co is used more often. One set uses high pressure steam, then passes the low pressure exhausted steam to the second, also known as master and slave, as in the British Rail Class 13 shunters at Tinsley Marshalling Yard

Glossary of North American railway terms
–
This page contains a list of terms, jargon, and slang used to varying degrees by railfans and railroad employees in the United States and Canada. Although not exhaustive, many of the entries in this list appear from time to time in specialist, inclusion of a term in this list does not necessarily imply its universal adoption by all railfans and railroad employees, and there may be significant regional variation in usage. 10 wheeler A steam locomotive with a 4-6-0 wheel arrangement 241 Procession of a train past a signal with verbal permission from the dispatcher. Derives from Rule 241, which is used to grant such permission under certain rule sets, normally, there are no manned services offered at these small stations. By analogy with U-boat, since with the Dash 7 line, the Soo covered up the Milwaukee Road name and logo on the orange locomotives with black paint, causing them to resemble bandits. Also often applied to similarly patched, second-hand locomotives, especially if the patches are crudely applied, a nickname for Guilford Rail System, in reference to the large G emblem on their locomotives and boxcars 2. Great Northern Railway Big hole When a train suffers a loss of all brake air and it refers to the air ports in the automatic brake valve, the emergency portion being the biggest port or hole. Bluebonnet One of two Santa Fe paint schemes, the standard freight scheme from 1972 until the BNSF merger was dark blue with yellow on the front, with the same color division as the warbonnet scheme. It is also known as Yellowbonnet, although a Slug and a B unit differ in terms of an engine, both serve the purpose of adding more tractive effort. A brakeman manually activated brakes on railroad cars before the advent of air brakes, sometimes built out of an ordinary automobile body, with flanged wheels added. It was driven by engines from 30 to 200 horsepower. Cadillac A nickname for EMD SD9 locomotives, in reference to their ride quality reminiscent of a Cadillac automobile. This nickname is said to have originated on the Southern Pacific Railroad, not a slug, it has its own diesel engine.

Glossary of New Zealand railway terms
–
This is a list of jargon commonly used by railfans in New Zealand. Introduced on DC4323 in 2001 after the Makihi collision, originally all locos were to have the Tranz Rail winged logo, but most carried TR block letters on the long hood and several locos did not carry any branding. Bobtail WW class locomotives before rebuilding Carvan Passenger carriage with a compartment at one end, classes AF. Originally built to relieve a shortage of guards vans and used on branch lines in place of a separate carriage and guards van. Cato Blue New Zealand Rail/Tranz Rail blue, yellow and grey livery used from 1990 to 2001, originally NZ Rail used a darker blue, which was changed to a lighter tone by Tranz Rail. Clockwork Orange 1970s orange and yellow used on DX class Coalies Coal train, particularly from Rapahoe. Also Genesis Energy coal trains between Mount Manganui and Weavers Crossing, but not for coal trains on the Rotowaro Industrial Branch, en, an abbreviation of hen, refers to the larger N class locomotive, and chicken refers to its underpowered M class assistant. Fairlie Flyer The passenger train between Washdyke Junction and Fairlie along the Fairlie Branch, also AB699 on the Pleasant Point Railway, which runs along part of the old branch line. Fiats NZR RM class 88 seater railcars Flying Tomato A simplified version of the Fruit Salad livery, applied to members of the DC, DF, DSC, and TR class locomotives in the 1980s as a cheaper alternative to the full Fruit Salad livery. The branch closed in 1933 and the no longer exists. The Hill The Johnsonville Line out of Wellington, or the section of the North Auckland Line between Newmarket and Remuera in Auckland. These wagons had lower sides than the L-series highsider wagons, and were used for loads that could not fit into a highsider or did not warrant the use of one. Lokey Locomotive on a bush tramway, abbreviation of the term locomotive, but shortened by bush workers and adopted by railway enthusiasts. It was first trialled on the carriages of the Parnassus Express and its name derives from the London, Midland and Scottish Railway, from whom the colour was originally sourced.

Glossary of United Kingdom railway terms
–
This page contains a list of jargon used to varying degrees by railfans and trainspotters in the United Kingdom, including nicknames for various locomotives and multiple units. Although not exhaustive, many of the entries in this list appear from time to time in specialist, inclusion of a term in this list does not necessarily imply its universal adoption by all railfans and enthusiasts, and there may be significant regional variation in usage. First Group are now favouring Neon schemes, Pancras, this service has subsequently been replaced by cross-London service on the Thameslink route. It is sometimes used referring to the line from Bedford to St Pancras. Bicycling Lion The British Railways emblem used from 1949 to 1956 and this name is derived from the fact the lion is standing astride the wheel like a cyclist – hence the nickname. This was replaced with the Ferret and Dartboard logo in 1956 as the British Railways logo, black Five A LMS Stanier Class 5 4-6-0. Class of steam locomotive built in the UK, named from their black mixed-traffic livery, the formal inspection usually requires the removal of the boiler from the locomotive and renewal of some parts such as the tubes. Additional annual safety inspections must also be undertaken, which may result in the locomotive being withdrawn from service until any faults are rectified, when the boiler ticket expires the locomotive cannot be used until the boiler has been reinspected and a new ticket obtained. Ironically, one of the workings of this class was a railfan special called the Bone Breaker which ended in a bufferstop collision. Bone Shaker London Underground A60 and A62 Stock, due to the ride of the old trains. The nickname was coined by an ITV News reporter during a report on the A Stocks last day of service on the Metropolitan Line. Brake van A heavy vehicle with powerful brakes which was attached to the rear of trains in the days when most wagons were not fitted with a continuous braking system. Its function was to supplement the locomotives braking power in slowing and stopping the train and to keep the couplings uniformly tight by selective light braking to avoid snatching and it also conveyed the train guard, hence its alternative name of guards van. Partly analogous to caboose and its synonyms, Brush British Rail Class 47 diesel-electric locomotive, also known as the Brush Type 4. Followers of this type are known as Brush bashers. It is still found on some London Underground lines, on secondary and preserved lines, the rail has two heads which led some people to assume that when one side became worn, the rail could be inverted and reinstalled for further service rather than being replaced. Coach Railway vehicle for use in passenger trains Coffee pot Applied to the shape of SR Q1 class steam locomotives Composite A passenger car with more than one class of accommodation provided. In earlier days of travel, first and second class

Railway coupling
–
A coupling is a mechanism for connecting rolling stock in a train. The design of the coupler is standard, and is almost as important as the gauge, since flexibility. The equipment that connects the couplings to the stock is known as the draft gear. The different types of coupling do not always have formal or official names and these couplings followed earlier tramway practice but were made more regular. The vehicles are coupled by hand using a hook and links with a turnbuckle that draws the vehicles together, in Britain, this is called a screw coupling. Vehicles have buffers, one at each corner on the ends and this arrangement limits the slack in trains and lessens shocks. The earliest buffers were fixed extensions of the frames. This coupling is still the standard in European countries, the link-and-pin coupling was the original style of coupling used on North American railways. After most railroads converted to semi-automatic Janney couplers, the link-and-pin survived on forestry railways, while simple in principle, the system suffered from a lack of standardisation regarding size and height of the links, and the size and height of the pockets. The link-and-pin coupler consisted of a body that received an oblong link. During coupling, a worker had to stand between the cars as they came together and guide the link into the coupler pocket. Once the cars were joined, the employee inserted a pin into a hole a few inches from the end of the tube to hold the link in place. This procedure was exceptionally dangerous and many brakemen lost fingers or entire hands when they did not get out of the way of the coupler pockets in time. Many more were killed as a result of being crushed between cars or dragged under cars that were coupled too quickly, brakemen were issued with heavy clubs that could be used to hold the link in position, but many brakemen would not use the club, and risked injury. The link-and-pin coupler proved unsatisfactory because, It made a connection between the cars, with too much slack action. There was no design, and train crews often spent hours trying to match pins. Crew members had to go between moving cars during coupling, and were injured and sometimes killed. The links and pins were often pilfered due to their value as scrap metal, john H. White suggests that the railroads considered this to be more important than the safety issue at the time

Variable gauge
–
A variable gauge system allows railway vehicles in a train to travel across a break of gauge caused by two railway networks with differing track gauges. For through-operation, a train must be equipped with special trucks holding variable gauge wheelsets containing a variable gauge axle, the gauge is altered by driving the train through a gauge changer or gauge changing facility. As the train passes through the changer, the wheels are unlocked, moved closer together, or further apart. Installed variable gauge systems exist within the network of Spain. A system for changing gauge, without need for stopping is widespread for passenger traffic in Spain, used in services run on a mix of dedicated high-speed lines, similar systems for freight traffic are still rather incipient, as the higher axle weight increases the technological challenge. Variable gauge axles help solve the problem of a break-of-gauge without having to resort to dual gauge tracks or transshipment, systems allow the adjustment between two gauges. No designs supporting more than two gauges are used, there are several variable gauge axle systems, Talgo-RD. The Talgo system has been in service in Portbou and Irun, on the Spanish-French border. CAF-BRAVA The BRAVA system was designed in 1968 by the Vevey Company. The system was called the Vevey axle. The design was obtained and improved by Construcciones y Auxiliar de Ferrocarriles. Being developed in 2002 for use between Europe and Russia, Japan Railways RTRI to be used on motorised axles. PKP SUW2000 system produced by ZNTK Poznań for Polish State Railways, the Montreux-Oberland Bernois railway, Switzerland in preparation by Prose of Winterthur 1,435 mm /1,000 mm. The variable gauge systems are not themselves all compatible, only the SUW2000 and Rafil Type V systems are interoperable. In 2009, at Roda de Barà near Tarragona, a Unichanger capable of four different VGA systems was under development. VGA is particularly important with international railway traffic because gauge changes tend to more often at international borders. The maximum speed of the equipped with the different technologies vary. Only CAF and Talgo produce high-speed VGA, allowing speeds up to 250 km/h, a gauge changer is a device which forces the gauge adjustment in the wheels

17.
Track gauge conversion
–
In rail transport, gauge conversion is the process of converting a railway from one rail gauge to another, through the alteration of the railway tracks. An alternative to gauge conversion is dual gauge track, or gauge conversion of the vehicles themselves. Rails may be too light for the loads imposed by broader-gauge railcars, in some cases, gauge-convertible sleepers are installed before the conversion of the track itself. The sleepers must be enough to take the wider of the two gauges, and must be able to accommodate the fittings for both the existing and the new gauges. In cases where the difference between the two gauges is small, such as 1,000 mm and 1,067 mm track, or 1,435 mm and 1,524 mm track, in those cases, gauntlet track is required. Timber sleepers are always gauge convertible, provided that they are long enough, if the new gauge is wider than the old, a shorter sleeper than would normally be used can be tolerated, provided it still allows for secure fastening of the wider track. Concrete sleepers cannot be converted as an afterthought, but must have the future fittings cast in place when manufactured, steel sleepers should have the extra fitting incorporated when manufactured, though it is theoretically possible to drill or weld new fittings to the sleeper after installation. A special gauge-convertible sleeper, with a chair for the Pandrol clip. In June 2008, the South Australian government announced that by 2012 the Adelaide metropolitan network would be converted from 1,600 mm broad gauge to standard gauge, consequently, broad-gauge timber sleepers are progressively being replaced with gauge-convertible concrete sleepers on the metropolitan rail network. As of 2016, however, gauge conversion had not commenced, narrow-gauge railways often have a significantly smaller structure gauge, and therefore the rolling stock used has a smaller loading gauge in both height and width. Conversion to a track gauge will often require enlargement of the structure gauge on bridges, under road overpasses. Embankments and cuts could need widening as well, the minimum curve radius of narrow-gauge railways is often less than on tracks with a wider gauge, so route deviations might be required to allow the radius of curves to be increased. Track centres at stations with multiple tracks may also have to be increased, in this instance, the loading gauge of the broad gauge and standard gauge lines are essentially the same. Where vehicles cross a change of gauge, they must either be equipped for a change of bogie or have adjustable gauge axles. For example passenger trains crossing between the 1,435 mm system in France and the 1,668 mm in Spain pass through an installation which adjusts their variable gauge axles. This temporary alteration to allow through working is generally referred to as gauge change, in the event, few have been so converted, but one such is Victorian Railways R class R766. Because boilers and fireboxes are in the way locomotives can be converted only to a wider gauge, about 1860, the Bristol and Exeter Railway converted five 1,435 mm gauge locomotives to 7 ft gauge, and later converted them back again. In the 19th century, in the US, some broad 1,524 mm gauge locomotives were designed for conversion to 1,435 mm gauge

18.
Dual gauge
–
A dual-gauge railway is a line of track that provides for trains of two separate track gauges. A mixed-gauge railway provides for more than two gauges, but is also a term sometimes used to denote dual-gauge. A dual-gauge track configuration usually consists of three rails, two rails, one for each gauge, plus a common rail--although at times, commonality is not possible. In an ordinary three-rail dual-gauge configuration, the two adjacent outer rails give provide each of the gauges, while the outer rail is common to trains of both gauges operating over it. This configuration is not to be confused with the electric current traction rail or a check or guard rail, in railways, the most important specification is that of rail gauge, the distance between the inner surfaces of the heads of the travel rails. A problem arises when different gauges outside of this tolerance meet one another, in allowing railway tracks of different gauges to share the same alignment, costs can be reduced, and infrastructure shared, e. g. platforms, bridges and tunnels etc. Dual gauge can replace two separate tracks by sharing one common running rail and one of the two outer rails which determine the gauge. However, there are complications and costs involved that may offset the savings. One issue is that points are more complex, and therefore more expensive, arrangements are necessary to ensure trains of both gauges can be safely signalled, track circuits and mechanical interlocking where provided must be operated through the common rail. Also, the rail will have an increased wear and tear over the other separate gauge rails. The following pairs of gauges can be dual-gauged without problem, standard gauge and 1,676 mm,3 ft and 3 ft 6 in, and 5 ft and 6 ft. Standard gauge and 1,600 mm can also be dual-gauged, albeit with lighter, narrow-footed rails and this last combination is of particular historical interest, as it was of strategic significance during World War II. If three-rail dual gauge is impossible, four-rail gauntlet track dual-gauge has to be used, the complications and difficulties outlined illustrate the benefits of standardised railway gauges, where possible. Alternatively the rails may be too light for the loads imposed by broader-gauge railcars, such potential problems can rule out dual-gauge as a feasible option, unless heavier rails are installed. Dual-gauge lines in Java were regauged from 4 ft 8 1⁄2 in to 3 ft 6 in during the Japanese administration in 1942-1943, regauging occurred only on the relatively short Brumbung-Kedungjati-Gundih main line and the Kedungjati-Ambarawa branch line, as the rest of the line was already dual-gauge. In Los Angeles the 3 ft 6 in Los Angeles Railway, the Colorado and Southern Railway had both standard and narrow gauge trackage, and had dual-gauge track between Denver, Colorado and Golden, until 1941. Similarly, a section of the Denver and Rio Grande Western Railroads Alamosa-Durango Line from Alamosa, the East Broad Top Railroad and Coal Company formerly had considerable dual-gauge trackage in its Mount Union, Pennsylvania yard. Alaska and British Columbia are proposing dual gauge,1,435 mm standard gauge and 914 mm, track so that a narrow gauge tourist train and standard gauge ore trains can share the right of way

Wheelset (rail transport)
–
A wheelset is the wheel - axle assembly of a railroad car. The frame assembly beneath each end of a car, railcar or locomotive that holds the wheelsets is called the bogie. Most North American freight cars have two bogies with two or three wheelsets, depending on the type of car, short freight cars generally have no bogies, two-axle cars operating on lines with sharp curves, such as Queensland Railways, used Grovers bogies. Rubber-tyred metros feature special wheelsets with rubber tyres outside of the special flanged steel wheels, the unusually large flanges on the steel wheels guide the bogie through standard railroad switches and in addition keep the train from derailing in case the tires deflate. Most train wheels have a taper of about 1 in 20. The semi-conical shape helps steer the wheel set around curves, so that the wheel flanges do not come in contact with the rail sides, the rails generally slant inwards at the same rate as the wheel conicity. As the wheels approach a curve, they tend to continue in a path due to the inertia of the rail car. This inertia makes the set to shift sideways as the track curves under it. Due to this fact, the diameter of the outer wheels needs to be greater than that of the inner ones. Since the wheels are joined rigidly by the axle, the outer wheels travel farther, for more information on this process, see Hunting oscillation. Queensland Railways, for its first hundred years, used cylindrical wheels, with non-inclined rails and cylindrical wheels, the wheel squeal from trains taking curves on that railway was slight.

Bogie
–
A bogie is a chassis or framework carrying wheels, attached to a vehicle, thus serving as a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport, while bogie is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used. A bogie in the UK, or a truck, wheel truck. In Indian English, bogie may also refer to a railway carriage. In South Africa, the bogie is often alternatively used to refer to a freight or goods wagon. The first standard gauge British railway to build coaches with bogies, an alternate configuration often is used in articulated vehicles, which places the bogies under the connection between the carriages or wagons. Most bogies have two axles, but some cars designed for heavy loads have more axles per bogie, heavy-duty cars may have more than two bogies using span bolsters to equalize the load and connect the bogies to the cars. Suspension to absorb shocks between the frame and the rail vehicle body, Common types are coil springs, or rubber airbags. At least one wheelset, composed of an axle with bearings and a wheel at each end The bolster, the railway car is supported at the pivot point on the bolster. Axle box suspensions absorb shocks between the bearings and the bogie frame. The axle box suspension usually consists of a spring between the frame and axle bearings to permit up-and-down movement, and sliders to prevent lateral movement. A more modern design uses solid rubber springs, brake equipment, Two main types are used, brake shoes that are pressed against the tread of the wheel, and disc brakes and pads. More modern, bolsterless bogie designs omit these features, instead taking advantage of the movement of the suspension to permit rotational movement. The Commonwealth bogie, manufactured by the English Steel Corporation under licence from the Commonwealth Steel Company in Illinois, fitted with SKF or Timken bearings, it was introduced in the late 1950s for all BR Mark 1 vehicles. It was a heavy, cast-steel design weighing about 6.5 long tons, with sealed roller bearings on the axle ends, the leaf springs were replaced by coil springs running vertically rather than horizontally. The advanced design gave a better quality than the BR1. The side frame of the bogie was usually of bar construction, with simple horn guides attached, the axle boxes had a cast-steel equaliser beam or bar resting on them. The bar had two steel coil springs placed on it and the bogie frame rested on the springs, the effect was to allow the bar to act as a compensating lever between the two axles and to use both springs to soften shocks from either axle

Dual coupling
–
Different types of railroad rolling stock have different couplers depending on the purpose and type of equipment being used and its intended destination. European rolling stock tend to use buffers and chain couplers while American rolling stock uses a Janney coupler or knuckle coupler and it is possible to mount both buffers and chain and knuckle couplers on the same car, provided that one can swing out of the way. Alternatively, either a lug to hold the chain is cast in the body of the coupler or a chain is mounted on top of the coupler and this is also done with an SA3 coupler built by SAB WABCO. The screw coupling is mounted on a hinge on the side of the knuckle coupler. Most Indian freight cars use the knuckle coupler alone, without buffers, exceptions are the new LHB coaches imported from Europe, and a few other makes of carriages converted to use knuckle couplers. Some Russian locomotives and wagons have buffers together with the central coupler, british locomotive-hauled passenger carriages adopted a dual coupling system in the 1950s. They have retractable buffers and a central Buckeye automatic knuckle coupler that lowers to reveal a hook for a chain coupling. When in use, a pin through the buckeye shank rests in the conventional hook, no chain is provided on dual-coupled vehicles, since the chain on the other vehicle can be used when the knuckle coupler is out of the way. Inter-stock coupling was with the coupler, while connection to the locomotive was with the buffer-and-chain system with a screw coupler. Today this dual coupling system has adopted for all loco-hauled passenger trains in Great Britain to allow faster shunting operations

Rail transport modelling
–
Railway modelling or model railroading is a hobby in which rail transport systems are modelled at a reduced scale. The earliest model railways were the railways in the 1840s. Electric trains appeared around the start of the 20th century, Model trains today are more realistic. Today modellers create model railway layouts, often recreating real locations, involvement ranges from possession of a train set to spending hours and large sums of money on a large and exacting model of a railroad and the scenery through which it passes, called a layout. Hobbyists, called railway modellers or model railroaders, may maintain models large enough to ride, modellers may collect model trains, building a landscape for the trains to pass through. They may also operate their own railroad in miniature, for some modellers, the goal of building a layout is to eventually run it as if it were a real railroad or as the real railroad did. If modellers choose to model a prototype, they may reproduce track-by-track reproductions of the railroad in miniature, often using prototype track diagrams. Layouts vary from a circle or oval of track to realistic reproductions of real places modelled to scale. Probably the largest model landscape in the UK is in the Pendon Museum in Oxfordshire, UK, the museum also houses one of the earliest scenic models – the Madder Valley layout built by John Ahern. This was built in the late 1930s to late 1950s and brought in realistic modelling, receiving coverage on both sides of the Atlantic in the magazines Model Railway News and Model Railroader. Bekonscot in Buckinghamshire is the oldest model village and includes a model railway, the worlds largest model railroad in H0 scale is the Miniatur Wunderland in Hamburg, Germany. The largest live steam layout, with 25 miles of track is Train Mountain in Chiloquin, Oregon, clubs often display models for the public. One specialist branch concentrates on larger scales and gauges, commonly using track gauges from 3.5 to 7.5 inches. Models in these scales are usually hand-built and powered by steam, or diesel-hydraulic. The Tech Model Railroad Club at MIT in the 1950s pioneered automatic control of track-switching by using telephone relays, the oldest society is The Model Railway Club, near Kings Cross, London, UK. As well as building model railways, it has 5,000 books, similarly, The Historical Model Railway Society at Butterley, near Ripley, Derbyshire specialises in historical matters and has archives available to members and non-members. The words scale and gauge seem at first interchangeable but their meanings are different, Scale is the models measurement as a proportion to the original, while gauge is the measurement between the rails. The size of engines depends on the scale and can vary from 700 mm tall for the largest ridable live steam scales such as 1,4, down to size for the smallest

Wood
–
Wood is a porous and fibrous structural tissue found in the stems and roots of trees, and other woody plants. It is a material, a natural composite of cellulose fibers which are strong in tension embedded in a matrix of lignin which resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, in a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots, Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber. In 2005, the stock of forests worldwide was about 434 billion cubic meters. As an abundant, carbon-neutral renewable resource, woody materials have been of intense interest as a source of renewable energy, in 1991 approximately 3.5 billion cubic meters of wood were harvested. Dominant uses were for furniture and building construction, a 2011 discovery in the Canadian province of New Brunswick discovered the earliest known plants to have grown wood, approximately 395 to 400 million years ago. Wood can be dated by carbon dating and in species by dendrochronology to make inferences about when a wooden object was created. People have used wood for millennia for many purposes, primarily as a fuel or as a material for making houses, tools, weapons, furniture, packaging, artworks. Constructions using wood date back ten thousand years, buildings like the European Neolithic long house were made primarily of wood. Recent use of wood has changed by the addition of steel. The year-to-year variation in tree-ring widths and isotopic abundances gives clues to the climate at that time. This process is known as growth, it is the result of cell division in the vascular cambium, a lateral meristem. These cells then go on to form thickened secondary cell walls, composed mainly of cellulose, hemicellulose, if the distinctiveness between seasons is annual, these growth rings are referred to as annual rings. Where there is little seasonal difference growth rings are likely to be indistinct or absent, if the bark of the tree has been removed in a particular area, the rings will likely be deformed as the plant overgrows the scar. It is usually lighter in color than that near the portion of the ring. The outer portion formed later in the season is known as the latewood or summerwood. However, there are differences, depending on the kind of wood

24.
Clerestory
–
In architecture, a clerestory is a high section of wall that contains windows above eye level. The purpose is to light, fresh air, or both. Similar structures have been used in vehicles to provide additional lighting, ventilation. The technology of the clerestory appears to originate in the temples of ancient Egypt, Clerestory appeared in Egypt at least as early as the Amarna period. In the Minoan palaces of Crete such as Knossos, by contrast, according to Biblical accounts, the Hebrew temple built by King Solomon featured clerestory windows made possible by the use of a tall, angled roof and a central ridgepole. The clerestory was used in the Hellenistic architecture of the periods of ancient Greek civilization. The Romans applied clerestories to basilicas of justice and to the basilica-like bath-houses and palaces, early Christian churches and some Byzantine churches, particularly in Italy, are based closely on the Roman basilica, and maintained the form of a central nave flanked by lower aisles on each side. The nave and aisles are separated by columns or piers, above which rises a wall pierced by clerestory windows, during the Romanesque period, many churches of the basilica form were constructed all over Europe. Many of these churches have wooden roofs with clerestories below them, some Romanesque churches have barrel vaulted ceilings with no clerestory. The development of the vault and ribbed vault made possible the insertion of clerestory windows. Initially the nave of an aisled and clerestoried church was of two levels, arcade and clerestory. During the Romanesque period a third level was inserted between them, a called the triforium. The triforium generally opens into space beneath the roof of the aisle. This became a feature of later Romanesque and Gothic large abbey. Sometimes another gallery set into the space above the triforium. This feature is found in some late Romanesque and early Gothic buildings in France, in smaller churches, clerestory windows may be trefoils or quatrefoils. In some Italian churches they are ocular, in most large churches, they are an important feature, both for beauty and for utility. The ribbed vaulting and flying buttresses of Gothic architecture concentrated the weight and thrust of the roof, in Gothic masterpieces, the clerestory is generally divided into bays by the vaulting shafts that continue the same tall columns that form the arcade separating the aisles from the nave

Mid-Continent Railway Museum
–
The Mid-Continent Railway Museum is a railroad museum in North Freedom, Wisconsin, United States. The museum consists of static displays as well as a 7-mile round trip ride aboard preserved railroad cars, during that time, railroads saw an unprecedented rate of expansion, growing in size in the United States from 93,000 to 254,037 miles of track. Three steam locomotives are currently under restoration to federal guidelines, the museum has 13 steam and 7 diesel locomotives including Chicago & North Western #1385 and over 100 other pieces of rolling stock. The depot is an original Chicago and North Western Railway depot from the town of Ableman, now known as Rock Springs. It was built in 1894 and moved to the museum to its current location in 1965, the depot consists of two seating areas separated by the ticket office. A gift shop now occupies the freight room. The interior was renovated following water damage during flooding in June 2008. In addition to the depot, other railroad structures moved to the location include a crossing shanty, crossing tower, section shed. Additional structures have been new to house and maintain the collection. The rail line used by Mid-Continent Railway Museum is a spur off the original Chicago & North Western Railway main line. With the development of the Illinois Iron mine in early 1903, by August 12, C&NW president Marvin Hughitt had arrived in North Freedom in person to announce that a branchline would be built. A second major mine, the Iroquois Mine was established in October not far from the new rail line, by December 1903, the 3-mile branchline was completed at a cost of $40,533. To support the number of miners in the area, a new town called La Rue was platted, named after William G. William La Rue was a mining pioneer who demonstrated the latest technological advancements in diamond drill technology could make iron mining in the area economically feasible. By November 1903, the development of the town shifted nearer to the Illinois Mine, one-half mile to the south, another townsite named Oliver was platted just east of La Rue, slightly closer to the Oliver Mining Company-owned Iroquois Mine, but no construction ever occurred. At its peak, the Illinois Mine was shipping between five and twelve train car loads daily over the C&NW branchline, but La Rue’s ironing mining days would be numbered. By June 1904, the mines were reaching depths of 400–500 feet at which water infiltrating into the mine shafts began being problematic, costs continued to grow as a result of the water infiltration until finally the Illinois Mine closed in 1908. By this time it was burdened by costs associated with pumping out 2,600 gallons of water per minute, a similar fate befell the Iroquois Mine in 1914, at which time it was pumping 4,500 gallons per minute from its mine shaft

Wisconsin
–
Wisconsin is a U. S. state located in the north-central United States, in the Midwest and Great Lakes regions. It is bordered by Minnesota to the west, Iowa to the southwest, Illinois to the south, Lake Michigan to the east, Michigan to the northeast, Wisconsin is the 23rd largest state by total area and the 20th most populous. The state capital is Madison, and its largest city is Milwaukee, the state is divided into 72 counties. Wisconsin is second to Michigan in the length of its Great Lakes coastline, Wisconsin is known as Americas Dairyland because it is one of the nations leading dairy producers, particularly famous for its cheese. Manufacturing, especially paper products, information technology, and tourism are major contributors to the states economy. The word Wisconsin originates from the given to the Wisconsin River by one of the Algonquian-speaking Native American groups living in the region at the time of European contact. French explorer Jacques Marquette was the first European to reach the Wisconsin River, arriving in 1673, subsequent French writers changed the spelling from Meskousing to Ouisconsin, and over time this became the name for both the Wisconsin River and the surrounding lands. English speakers anglicized the spelling from Ouisconsin to Wisconsin when they began to arrive in numbers during the early 19th century. The legislature of Wisconsin Territory made the current spelling official in 1845, the Algonquin word for Wisconsin and its original meaning have both grown obscure. Interpretations vary, but most implicate the river and the red sandstone that lines its banks, other theories include claims that the name originated from one of a variety of Ojibwa words meaning red stone place, where the waters gather, or great rock. Wisconsin has been home to a variety of cultures over the past 12,000 years. The first people arrived around 10,000 BCE during the Wisconsin Glaciation and these early inhabitants, called Paleo-Indians, hunted now-extinct ice age animals such as the Boaz mastodon, a prehistoric mastodon skeleton unearthed along with spear points in southwest Wisconsin. After the ice age ended around 8000 BCE, people in the subsequent Archaic period lived by hunting, fishing, agricultural societies emerged gradually over the Woodland period between 1000 BCE to 1000 CE. Toward the end of period, Wisconsin was the heartland of the Effigy Mound culture. Later, between 1000 and 1500 CE, the Mississippian and Oneota cultures built substantial settlements including the village at Aztalan in southeast Wisconsin. The Oneota may be the ancestors of the modern Ioway and Ho-Chunk tribes who shared the Wisconsin region with the Menominee at the time of European contact, the first European to visit what became Wisconsin was probably the French explorer Jean Nicolet. He canoed west from Georgian Bay through the Great Lakes in 1634, pierre Radisson and Médard des Groseilliers visited Green Bay again in 1654–1666 and Chequamegon Bay in 1659–1660, where they traded for fur with local Native Americans. In 1673, Jacques Marquette and Louis Jolliet became the first to record a journey on the Fox-Wisconsin Waterway all the way to the Mississippi River near Prairie du Chien

British Rail Mark 3
–
The British Rail Mark 3 is a type of passenger carriage developed in response to growing competition from airlines and the car in the 1960s. A variant of the Mark 3 became the rolling stock for the High Speed Train, originally conceived as locomotive-hauled coaching stock, the first coaches built were for the prototype HST in 1972. Production coaches entered service between 1975 and 1988, and multiple-unit designs based on the Mark 3 bodyshell continued to be built until the early 1990s. The Mark 3 and its derivatives are widely recognised as a safe and reliable design, at the end of 1968 proposals were submitted to the Commercial and Operating Departments of British Rail for a new fleet of third-generation standard coaching stock, designed to run at 125 mph. The rapid development required for the HST in 1969 made the Mark 3 coach design the obvious choice for this train, the Mark 3 looks similar to Mark 2D, 2E and 2F coaches, but is of a completely different design. It has a roof and under-frame skirt compared with a smooth roof. An important advance over its predecessor was the adoption of air suspension between the body and the bogies, giving an exceptionally smooth ride. The lighting and air-conditioning fittings were for the first time integrated into the ceiling panels, other new features were the pneumatically operated automatic gangway doors triggered by pressure pads under the floor. A speed-operated central door-locking system for the manually operated slam-doors was installed from 1993, the main difference between the HST vehicles and the loco-hauled Mark 3A relate to electrical supply arrangements. These convert the train supply to 3-phase 415/240 V50 Hz AC to power air conditioning, the two types are non-interconnectable in service conditions. The other main difference is the lack of buffers on HST coaches, the later Mark 3B build provided first class loco-hauled vehicles for the West Coast Main Line. These are similar to Mark 3As, but have an improved motor alternator unit with compound-wound motor, in 1973 the prototype HST was evaluated as an 8-coach formation. The two spare coaches,2903 and 2904, were rebuilt and redeployed in the Royal Train, a much reduced number of coaches were manufactured, requiring many Mark 2D, 2E and 2F coaches to remain in service. The table below lists manufacturing variants as built, showing the quantity of each type/designation, see British Railway Coach Designations for the meaning of RSB, TRUK, BFO etc. Since 1977, the Royal Train has included some specially equipped Mark 3 coaches, Mark 3s remain in service as part of HSTs with CrossCountry, East Midlands Trains, Great Western Railway and Virgin Trains East Coast much as they have since introduced. These were refurbished when their operators were privatised, with all except East Midlands Trains’ receiving new seats between 2006 and 2009, the introduction by Virgin CrossCountry of 220/221 Voyagers in the early 2000s rendered many Mark 3s surplus. After periods of storage, all have now returned to service with other operators, the introduction by Virgin Trains of Class 390 Pendolinos in the early 2000s resulted in the withdrawal of the locomotive hauled Mark 3s. Some were cascaded to One to replace Mark 2s on the Great Eastern Main Line, most were placed in store at Long Marston

Canadian English
–
Canadian English is the set of varieties of the English language native to Canada. A larger number,28 million people, reported using English as their dominant language, 82% of Canadians outside the province of Quebec reported speaking English natively, but within Quebec the figure was just 7. 7% as most of its residents are native speakers of Quebec French. Canadian English contains elements of British English and American English, as well as many Canadianisms, the construction of identities and English-language varieties across political borders is a complex social phenomenon. The term Canadian English is first attested in a speech by the Reverend A. Constable Geikie in an address to the Canadian Institute in 1857, Canadian English is the product of five waves of immigration and settlement over a period of more than two centuries. Studies on earlier forms of English in Canada are rare, yet connections with other work to historical linguistics can be forged, an overview of diachronic work on Canadian English, or diachronically-relevant work, is Dollinger. Until the 2000s, basically all commentators on the history of CanE have argued from the language-external history, an exception has been in the area of lexis, where Avis et als Dictionary of Canadianisms on Historical Principles, offered real-time historical data though its quotations. Recently, historical linguists have started to study earlier Canadian English on historical linguistic data, dCHP-1 is now available in open access. )Most notably, Dollinger pioneered the historical corpus linguistic approach for English in Canada with CONTE and offers a developmental scenario for 18th and 19th century Ontario. Recently, Reuter, with a 19th-century newspaper corpus from Ontario, has confirmed the scenario laid out in Dollinger, Canadian spelling of the English language combines British and American conventions. Words such as realize and paralyze are usually spelled with -ize or -yze rather than -ise or -yse, french-derived words that in American English end with -or and -er, such as color or center, often retain British spellings. While the United States uses the Anglo-French spelling defense and offense, some nouns, as in British English, take -ice while matching verbs take -ise – for example, practice and licence are nouns while practise and license are the respective corresponding verbs. Canadian spelling sometimes retains the British practice of doubling consonants when adding suffixes to words even when the syllable is not stressed. Compare Canadian travelled, counselling, and marvellous to American traveled, counseling, in American English, such consonants are only doubled when stressed, thus, for instance, controllable and enthralling are universal. In other cases, Canadians and Americans differ from British spelling, such as in the case of nouns like curb and tire, Canadian spelling conventions can be partly explained by Canadas trade history. For instance, the British spelling of the word cheque probably relates to Canadas once-important ties to British financial institutions, Canadas political history has also had an influence on Canadian spelling. Canadas first prime minister, John A. Macdonald, once directed the Governor General of Canada to issue an order-in-council directing that government papers be written in the British style, a contemporary reference for formal Canadian spelling is the spelling used for Hansard transcripts of the Parliament of Canada. Many Canadian editors, though, use the Canadian Oxford Dictionary, often along with the chapter on spelling in Editing Canadian English, and, throughout part of the 20th century, some Canadian newspapers adopted American spellings, for example, color as opposed to the British-based colour. Some of the most substantial historical spelling data can be found in Dollinger, the use of such spellings was the long-standing practice of the Canadian Press perhaps since that news agencys inception, but visibly the norm prior to World War II. The practice of dropping the letter u in such words was also considered a labour-saving technique during the days of printing in which movable type was set manually

International Union of Railways
–
The UIC or International Union of Railways is an international rail transport industry body. The railways of Europe originated as separate concerns, and there were many border changes after World War I. Colonial railways were the responsibility of the mother country, into this environment the UIC was created on 20 October 1922, with the aim of standardising industry practices. Ticket revenue sharing was undertaken with the UIC Franc currency equivalent. UIC classification and UIC Country Codes allowed precise determination of rolling stock capabilities and ownership, the UICs mission is to promote rail transport at world level and meet the challenges of mobility and sustainable development. They were soon joined by the USSR, the Middle East, today, the UIC has 194 members across 5 continents. Of these there are,73 active members 68 associate members 53 affiliate members On 12 November, in order to provide a common understanding and reduce potential confusion, the UIC has established standard international railway terminology and a trilingual thesaurus of terms. The thesaurus was the result of cooperation with the European Conference of Ministers of Transport and was published in 1995, the UIC has established systems for the classification of locomotives and their axle arrangements, coaches and goods wagons. UIC plays an important role in standardization of parts, data. Therefore, UIC codes are developed since the beginning of UICs work, a new term for these UIC leaflets is used by UIC for better understanding, International Railway Standard. Some UIC codes are, UIC568 The 13-corded standardized connection cable with connector is used to transmit data, UIC 592-2 Large containers for transport on wagons - Technical conditions to be fulfilled by large containers accepted for use in international traffic. Describes the classes and categories of large containers, handling characteristics, identification markings, UIC 592-3 Large containers, swap bodies and transport frames for horizontal transhipment - Standard report on acceptance tests. UIC 592-4 Swap bodies for grab handling and spreader gripping - Technical conditions, Swap bodies are the removable superstructures of road transport vehicles. Their dimensions and some of their fittings are standardised, particularly dimensions, strength parameters and securing devices, of the road vehicle, UIC 596-5 Transport of road vehicles on wagons - Technical organisation - Conveyance of semi-trailers with P coding or N coding on recess wagons. This leaflet sets out regulations and provisions for semi-trailers with normal road transport characteristics for conveyance on fixed-recess carrier wagons, the provisions are valid for semi-trailers, gantry equipment/industrial trucks with grab handles, recess wagon types 1a and 1b in accordance with UIC Leaflet 571-4. UIC 596-6 Conveyance of road vehicles on wagons - Technical organisation - Conditions for coding combined-transport load units, the provisions aim to facilitate LU identification to speed-up international traffic movements. They are applicable to semi-trailers, swap bodies, roller units loaded on wagons, African Union of Railways, similar organisation focused on Africa Association of American Railroads International Union of Public Transport, which covers passenger railways, especially in cities

Vehicle
–
A vehicle is a mobile machine that transports people or cargo. Typical vehicles include wagons, bicycles, motor vehicles, railed vehicles, Land vehicles are classified broadly by what is used to apply steering and drive forces against the ground, wheeled, tracked, railed or skied. ISO 3833-1977 is the standard, also used in legislation, for road vehicles types, terms. Boats were used between 4000 BC-3000 BC in Sumer, ancient Egypt and in the Indian Ocean, there is evidence of camel pulled wheeled vehicles about 3000–4000 BC. Wheeled vehicles pulled by men and animals ran in grooves in limestone, in 200 CE, Ma Jun built a south-pointing chariot, a vehicle with an early form of guidance system. Railways began reappearing in Europe after the Dark Ages, the earliest known record of a railway in Europe from this period is a stained-glass window in the Minster of Freiburg im Breisgau dating from around 1350. In 1515, Cardinal Matthäus Lang wrote a description of the Reisszug, the line originally used wooden rails and a hemp haulage rope and was operated by human or animal power, through a treadwheel. 1769 Nicolas-Joseph Cugnot is often credited with building the first self-propelled mechanical vehicle or automobile in 1769. In Russia, in the 1780s, Ivan Kulibin developed a human-pedalled, three-wheeled carriage with modern features such as a flywheel, brake, gear box and bearings, however and it was introduced by Drais to the public in Mannheim in summer 1817. 1903 Wright brothers flew the first controlled, powered aircraft 1907 First helicopters Gyroplane no.1, there are over 1 billion bicycles in use worldwide. In 2002 there were an estimated 590 million cars and 205 million motorcycles in service in the world, at least 500 million Chinese Flying Pigeon bicycles have been made, more than an other single model of vehicle. The most-produced model of vehicle is the Honda Super Cub motorcycle. The most-produced car model is the Toyota Corolla, with at least 35 million made by 2010, by far, most vehicles use wheels which employ the principle of rolling to enable displacement with very little rolling friction. It is essential that a vehicle have a source of energy to drive it, energy can be extracted from the surrounding environment, as in the case of a sailboat, a solar-powered car or a streetcar. Energy can also be stored, in any form, provided it can be converted on demand, the most common type of energy source is fuel. Batteries also facilitate the use of motors, which have their own advantages. On the other hand, batteries have low densities, short service life, poor performance at extreme temperatures. Like fuel, batteries store energy and can cause burns

Cargo
–
Multi-modal container units, designed as reusable carriers to facilitate unit load handling of the goods contained, are also referred to as cargo, specially by shipping lines and logistics operators. Similarly, aircraft ULD boxes are also documented as cargo, with associated packing list of the contained within. When empty containers are shipped each unit is documented as a cargo and when goods are stored within, seaport terminals handle a wide range of maritime cargo. Automobiles are handled at many ports and are carried on specialized roll-on/roll-off ships. Break bulk cargo is typically stacked on pallets and lifted into. The volume of bulk cargo has declined dramatically worldwide as containerization has grown. One way to secure break bulk and freight in intermodal containers is by using Dunnage Bags, bulk cargo, such as salt, oil, tallow, and scrap metal, is usually defined as commodities that are neither on pallets nor in containers. Bulk cargoes are not handled as individual pieces, the way heavy-lift, alumina, grain, gypsum, logs, and wood chips, for instance, are bulk cargoes. Neo-bulk cargo comprises individual units that are counted as they are loaded and unloaded, in contrast to bulk cargo that is not counted, containers are the largest and fastest growing cargo category at most ports worldwide. Containerized cargo includes everything from auto parts, machinery and manufacturing components to shoes and toys to frozen meat, air cargo, commonly known as air freight, is collected by firms from shippers and delivered to customers. Aircraft were first used for carrying mail as cargo in 1911, eventually manufacturers started designing aircraft for other types of freight as well. There are many commercial aircraft suitable for carrying cargo such as the Boeing 747 and the bigger An‑124, such large aircraft employ quick-loading containers known as unit load devices, much like containerized cargo ships. The ULDs are located in the front section of the aircraft, most nations own and utilize large numbers of military cargo aircraft such as the C‑17 Globemaster III for logistical needs. Popular commercial aircraft transformed to an aircraft such as Saab 340A is designed for high revenue. Trains are capable of transporting a number of containers that come from shipping ports. Trains are also used for the transportation of water, cement, grain, steel, wood and they are used because they can carry a large amount and generally have a direct route to the destination. Under the right circumstances, freight transport by rail is more economic and energy efficient than by road, the main disadvantage of rail freight is its lack of flexibility. For this reason, rail has lost much of the business to road transport

33.
Passenger
–
A passenger is a person who travels in a vehicle but bears little or no responsibility for the tasks required for that vehicle to arrive at its destination or otherwise operate the vehicle. Passengers are people who ride on buses, passenger trains, airliners, ships, ferryboats, historically, the concept of the passenger has existed for as long as man has been able to create means of transportation capable of carrying more people than were needed to operate the vessel. Crew members, as well as the driver or pilot of the vehicle, are not considered to be passengers. In railway parlance, passenger, as well as being the end user of a service, is also a categorisation of the type of rolling stock used, in the British case, there are several categories of passenger train. These categories include, Express passenger, which long distance. Semi-fast express passenger, a type of service that is high speed, local passenger, the lowest category of British passenger train, which provides a service that stops at all stations between major destinations, for the benefit of local populations. In transportation, a no pax trip is a trip without passengers, for example, no-pax flights are freight, ferry and positioning flights. In most jurisdictions, laws have been enacted that dictate the legal obligations of the owner of a vehicle or vessel, or of the driver or pilot of the same, towards the passengers. In other situations, however, guest statutes may limit the ability of passengers to sue the driver of the vehicle over an accident, many places require cars to be outfitted with measures specifically for the protection of passengers, such as passenger-side air bags. With respect to passengers on vehicles or vessels, both national laws and international treaties require that the carrier act with a certain standard of care. The number of passengers that a vehicle or vessel may legally carry is defined as its seating capacity, revenue passenger Media related to Passengers at Wikimedia Commons

Passenger car (rail)
–
A passenger car is a piece of railway rolling stock that is designed to carry passengers. The term passenger car can also be associated with a car, baggage, dining, railway post office. Up until about the end of the 19th century, most passenger cars were constructed of wood, the first passenger trains did not travel very far, but they were able to haul many more passengers for a longer distance than any wagons pulled by horses. As railways were first constructed in England, so too were the first passenger cars, one of the early coach designs was the Stanhope. It featured a roof and small holes in the floor for drainage when it rained, the only problem with this design is that the passengers were expected to stand for their entire trip. The first passenger cars in the United States resembled stagecoaches and they were short, often less than 10 ft long and had two axles. British railways had a start on American railroads, with the first bed-carriage being built there as early as 1838 for use on the London and Birmingham Railway. Britains early sleepers, when made up for sleeping, extended the foot of the bed into a section at the end of the carriage. The cars were too short to allow more than two or three beds to be positioned end to end. Britains Royal Mail commissioned and built the first Travelling Post Office cars in the late 1840s as well. These cars resembled coaches in their short wheelbase and exterior design, when not in use, the hook would swivel down against the side of the car to prevent it from catching obstacles. As locomotive technology progressed in the century, trains grew in length. Passenger cars, particularly in America, grew along with them, first getting longer with the addition of a second truck, early American sleeping cars were not compartmented, but by the end of the 19th century they were. The compartments in the sleepers were accessed from a side hall running the length of the cars. Many American passenger trains, particularly the long ones, included a car at the end of the train called an observation car. Until about the 1930s, these had a platform at the rear. These evolved into the end car, usually with a rounded end which was still called an observation car. The interiors of observation cars varied, many had special chairs and tables

35.
Railcar
–
A railcar, in British English and Australian English, is a self-propelled railway vehicle designed to transport passengers. The term railcar is usually used in reference to a train consisting of a single coach, some railways, e. g. the Great Western Railway, used the term Railmotor. If it is able to pull a train, it is rather called a motor coach or a motor car. In its simplest form it may be more than a motorised version of a railway handcar. The term is also used as an alternative name for the small types of multiple unit which consist of more than one coach. The term is used more generally now in Ireland to refer to any multiple unit. In North America the term “railcar” has a broader meaning. Railcars have also employed on premier services. It is possible for several railcars to run together, each with its own driver, the reason for this was to keep costs down, since small railcars were not always fitted with multiple unit control. There are also articulated railcars, with bogies under the point between the rather than two pivoting bogies under each carriage. Like many high-end DMUs, these vehicles are made of 2 or 3 connected units that are coupled as “married pairs or triplets”. Passengers may walk between the married pair units without having to open or pass through doors, unit capacities range from 70 to over 300 seated passengers. The equipment is highly customisable with a variety of engine, transmission, coupler systems. This restriction makes it impossible to operate them on existing rail corridors with conventional passenger rail service. The light regional railcars are used by a number of railroads in Germany amongst others, railbuses were used commonly in countries such as Germany, Italy, France, United Kingdom, the Czech Republic and Sweden. A type of known as a Pacer is still commonly used in the United Kingdom. In Australia, where they were often called Rail Motors, railcars were used for passenger services on lightly used lines. In France they are called an Autorail, once very common their use died out as local lines were closed

36.
Multiple unit
–
Multiple units are self-propelled train carriages capable of coupling with other units of the same or similar type and still being controlled from one driving cab. Often these are passenger trainsets consisting of more than one carriage, single self-propelling carriages are multiple units if capable of operating with other units. Multiple units are classified by their source and are of two main types, electric multiple unit or diesel multiple unit. Diesel-powered units may be classified by their transmission type, diesel-electric. Locomotives utilising multiple-unit train control are not multiple units, multiple-unit train control was first used in Electric Multiple Units in the 1890s. This allowed electrically-powered rapid transit trains to be operated from a driving position. Early users of multiple units include the Liverpool Overhead Railway. The United Kingdom and France had many examples of steam trains, or autotrains. These provided many of the benefits of a multiple unit. While a professor at the University of Denver, Sidney Howe Short conducted important experiments which established that multiple unit powered cars were a way to operate trains. Most MUs are powered either by traction motors, receiving their power through a rail or overhead wire. Diesel-electric multiple units have an engine that drives a generator producing electricity to drive traction motors in a similar fashion to a diesel-electric locomotive. A multiple-unit has the power and traction components as a locomotive. In many cases these cars can only propel themselves when they are part of the unit and it is not necessary for every single car in an MU to be motorized. Therefore, MU cars can be motor units or trailer units, instead of motors, trailing units can contain supplementary equipment such as air compressors, batteries, etc. trailer cars may also be fitted with a driving cab. In most cases, MU trains can only be driven/controlled from dedicated cab cars, an example of this arrangement is the NJ Transit Arrows. Virtually all rapid transit rolling stock, such as used on the New York City Subway, the London Underground. Most trains in the Netherlands and Japan are MUs, making them suitable for use in areas of population density

Indian English
–
Indian English is any of the forms of English characteristic of India. English is a lingua franca of India, though English is one of the two official languages of the Union Government of India, only a few hundred thousand Indians have English as their first language. Among women, the percentages were 83 percent speaking no English,17 percent speaking at least some English. The number of English-medium school students in India increased from over 15 million in 2008–09 to 29 million by 2013–14, in December 2015, the Supreme Court of India ruled that English is the only court language. India ranks 22 out of 72 countries in the 2016 EF English Proficiency Index published by the EF Education First, the index gives the country a score of 57.30 indicating moderate proficiency. India ranks 4th out of 19 Asian countries included in the index, among Asian countries, Singapore, Malaysia and the Philippines received higher scores than India. Indian English generally uses the Indian numbering system, idiomatic forms derived from Indian literary languages and vernaculars have been absorbed into Indian English. Nevertheless, there remains general homogeneity in phonetics, vocabulary, English language public instruction began in India in the 1830s during the rule of the East India Company. In 1835, English replaced Persian as the language of the Company. Lord Macaulay played a role in introducing English and western concepts to education in India. He supported the replacement of Persian by English as the language, the use of English as the medium of instruction in all schools. Throughout the 1840s and 1850s, primary-, middle-, and high-schools were opened in districts of British India. In 1857, just before the end of Company rule, universities modelled on the University of London and using English as the medium of instruction were established in Bombay, Calcutta and Madras. During subsequent Crown Rule in India, or the British Raj, lasting from 1858 to 1947 and this was driven in part by the gradually increasing hiring of Indians in the civil services. At the time of Indias independence in 1947, English was the only lingua franca in the country. After Indian Independence in 1947, Hindi was declared the first official language, due to protests from Tamil Nadu and other non-Hindi-speaking states, it was decided to temporarily retain English for official purposes until at least 1965. By the end of period, however, opposition from non-Hindi states was still too strong to have Hindi declared the sole language. With this in mind, the English Language Amendment Bill declared English to be an associate language until such time as all non-Hindi States had agreed to its being dropped and this hasnt yet occurred, and it is still widely used

Coach (rail)
–
A passenger car is a piece of railway rolling stock that is designed to carry passengers. The term passenger car can also be associated with a car, baggage, dining, railway post office. Up until about the end of the 19th century, most passenger cars were constructed of wood, the first passenger trains did not travel very far, but they were able to haul many more passengers for a longer distance than any wagons pulled by horses. As railways were first constructed in England, so too were the first passenger cars, one of the early coach designs was the Stanhope. It featured a roof and small holes in the floor for drainage when it rained, the only problem with this design is that the passengers were expected to stand for their entire trip. The first passenger cars in the United States resembled stagecoaches and they were short, often less than 10 ft long and had two axles. British railways had a start on American railroads, with the first bed-carriage being built there as early as 1838 for use on the London and Birmingham Railway. Britains early sleepers, when made up for sleeping, extended the foot of the bed into a section at the end of the carriage. The cars were too short to allow more than two or three beds to be positioned end to end. Britains Royal Mail commissioned and built the first Travelling Post Office cars in the late 1840s as well. These cars resembled coaches in their short wheelbase and exterior design, when not in use, the hook would swivel down against the side of the car to prevent it from catching obstacles. As locomotive technology progressed in the century, trains grew in length. Passenger cars, particularly in America, grew along with them, first getting longer with the addition of a second truck, early American sleeping cars were not compartmented, but by the end of the 19th century they were. The compartments in the sleepers were accessed from a side hall running the length of the cars. Many American passenger trains, particularly the long ones, included a car at the end of the train called an observation car. Until about the 1930s, these had a platform at the rear. These evolved into the end car, usually with a rounded end which was still called an observation car. The interiors of observation cars varied, many had special chairs and tables

Goods wagon
–
Goods wagons or freight wagons are unpowered railway vehicles that are used for the transportation of cargo. At the beginning of the era, the vast majority of goods wagons were four-wheeled vehicles of simple construction. These were almost exclusively small covered wagons, open wagons with side-boards, over the course of time, an increasing number of specialised wagons were developed. Special wagons for specific purposes or wagons with special features were already being introduced around 1850 by private companies, amongst these were tank wagons and numerous refrigerated vans. In countries like Germany, wagon hire firms procured large numbers of these wagons, in the early days of the railway, goods trains still ran at top speeds of only about 20 mph. However, the introduction of through brakes using air pipes from the 1920s enabled higher speeds to be safely achieved, the Deutsche Bahn even has goods wagons cleared for high-speed rail travel at up to 100 mph. In Europe, the first agreements were struck early on between the national state railways and private companies for the mutual use of each other’s goods wagons. Around 1850, the Union of German Railway Administrations drew up regulations for the standardisation of dimensions, the formation of the Prussian State Railway Union in 1881 encouraged the emergence of wagon classes built to standard norms. One further European milestone was the formation of the German State Railway Wagon Association on 1 April 1909. With the participation of all the German state railways, it created a pool of goods wagons. In addition, they all had standardised inscriptions and red-brown livery, in order to standardise future procurements, a total of 11 wagon classes were defined. From 1939, wagons were developed primarily from a point of view and were known as wartime classes. After the war, in East Germany, some pre-war goods wagon classes were given a new lease of life as ‘reconstructed goods wagons’, since the Union of Private Goods Wagon Companies was founded in 1921, the interests of private transport organisations in Germany has been jointly represented. The Union has around 100 members who own 50,000 goods wagons, in 2007, they transported 361,000,000 t of goods. Since 1922, the agreement for the use of goods wagons in international traffic has regulated the exchange of goods wagons in Europe. In addition, international goods wagon fleets were created in 1953 in Western Europe with the Europ-Verband, during the second half of the 20th century, national goods wagon classes in Europe were increasingly replaced by Union internationale des chemins de fer standard wagons. Since 1964, all goods wagons in Germany, for example, have had to be classified using the UIC goods wagon classification system, lowmacs Covered wagons or vans have a fixed roof and are mainly used for the transportation of part-load goods or parcels. Today these are divided into, Ordinary classes Special classes, which are distinguished by their large loading volumes

Standard-gauge
–
The standard gauge is a widely used railway track gauge. Approximately 55% of the lines in the world are this gauge, all high-speed rail lines, except those in Russia, Uzbekistan, and Finland, are standard gauge. The distance between the edges of the rails is defined to be 1435 mm except in the United States. It is also called the UIC gauge or UIC track gauge, as railways developed and expanded, one of the key issues was the track gauge to be used. The result was the adoption throughout a large part of the world of a gauge of 1435 mm. In North East England, some lines in colliery areas were 4 ft 8 in. All these lines had been widened to standard gauge by 1846, parts of the United States, mainly in the Northeast, adopted the same gauge, because some early trains were purchased from Britain. However, until well into the half of the 19th century, Britain. The American gauges converged as the advantages of equipment interchange became increasingly apparent, notably, all the 5 ft broad gauge track in the South was converted to standard gauge over the course of two days beginning on 31 May 1886. See Track gauge in the United States, snopes categorized this legend as false, but commented that. It is perhaps more fairly labelled as True, but for trivial, the historical tendency to place the wheels of horse-drawn vehicles approximately 5 feet apart probably derives from the width needed to fit a carthorse in between the shafts. Others were 4 ft 4 in or 4 ft 7 1⁄2 in, the English railway pioneer George Stephenson spent much of his early engineering career working for the coal mines of County Durham. He favoured 4 ft 8 in for wagonways in Northumberland and Durham, the Hetton and Springwell wagonways also used this gauge. Stephensons Stockton and Darlington railway was primarily to transport coal from mines near Shildon to the port at Stockton-on-Tees. The initial gauge of 4 ft 8 in was set to accommodate the existing gauge of hundreds of horse-drawn chaldron wagons that were already in use on the wagonways in the mines. The railway used this gauge for 15 years before a change was made to 4 ft 8 1⁄2 in gauge, George Stephenson used the 4 ft 8 1⁄2 in gauge for the Liverpool and Manchester Railway, authorised in 1826 and opened 30 September 1830. The success of this led to Stephenson and his son Robert being employed to engineer several other larger railway projects. Monkland and Kirkintilloch Railway, authorised 1824 and opened 1825, used 4 ft 6 in, Dundee and Newtyle Railway, authorised 1829 and opened 1831, used 4 ft 6 1⁄2 in

Standing passenger
–
In urban public transport, provision is made for standing passengers, often called straphangers or standees, to rationalize operation and to provide extra capacity during rush hour. On crowded rapid transit lines, while most travelers may be seated during off-peak services. The longer the journey, the less willing passengers are to stand, on intercity rail or coach services, the willingness among passengers to stand is often low, or it may even be prohibited, with reserved seating to ensure that all passengers can be seated. In aviation, safety measures require all passengers and crew to be seated during take-off and landing, however, in 2010, Ryanair, a low-cost airline proposed a vertical seat design for use by standing passengers on its aircraft. The seated to standing ratio is the ratio between the number of passengers that can be seated and the number of standing passengers on a transport vehicle. A higher standing ratio allows for passengers in a given area. This metric is normally limited to mass transit, due to intercity transport normally only offering seated travel. On longer haul services, bilevel cars are used to allow for increased seating, though this increases the dwell time at stations. Passengers per square metre is a quality of service used to determine the standard of comfort provided to standing passengers in a transportation vehicle. Multiplying this number by the total available standing area on a vehicle gives the total standing passenger capacity, bus services in Europe operate at about four passengers per square metre. Standing passengers are susceptible to suffering falls and other injuries, particularly elderly people, shorter people and children may not be able to reach ceiling-mounted handles, straps, or rails. Porous cloth straps are hard to clean, and are being replaced by rubber or plastic straps, and metal fixtures often made of stainless steel

Head-end power
–
In rail transport, head-end power or electric train supply is the electrical power distribution system on a passenger train. The power source, usually a locomotive at the front or head of a train, provides the electricity used for lighting, electrical, the maritime equivalent is hotel electric power. Oil lamps were introduced in 1842 to light trains, economics drove the Lancashire and Yorkshire Railway to replace oil with coal gas lighting in 1870, but a gas cylinder explosion on the train led them to abandon the experiment. Oil-gas lighting was introduced in late 1870, high steam consumption led to abandonment of the system. Three trains were started in 1883 by London, Brighton and South Coast Railway with electricity generated on board using a dynamo driven from one of the axles and this charged a lead-acid battery in the guards van, who operated and maintained the equipment. The system successfully provided electric lighting in the train and this accident prompted railways to adopt electricity for lighting the trains. Starting in the 1930s, air conditioning became available on railcars, with the energy to run them being provided by mechanical power take offs from the axle, small dedicated engines or propane. The resulting separate systems of lighting power, steam heat, and engine-driven air conditioning increased the maintenance workload, head-End Power would allow for a single power source to handle all these functions and more for an entire train. Originally, trains hauled by a locomotive would be provided with a supply of steam from the locomotive for heating the carriages. When diesel locomotives and electric locomotives replaced steam, the heating was then supplied by a steam-heat boiler. This was oil-fired or heated by an electric element, later carriage designs abolished the steam-heat apparatus, and made use of the ETH supply for heating, lighting, ventilation, air conditioning, fans, sockets and kitchen equipment in the train. In recognition of this ETH was eventually renamed Electric Train Supply, each coach has an index relating to the maximum consumption of electricity that it could use. The sum of all the indices must not exceed the index of the locomotive, one ETH index unit equals 5 kW, a locomotive with an ETH index of 95 can supply 475 kW of electrical power to the train. In response, the railroad installed higher capacity generators on the assigned to these trains. The cars used steam from the locomotive for heating, when diesel locomotives were introduced to passenger service, they were equipped with steam generators to provide steam for car heating. However, the use of generators and batteries persisted for many years. This was an evolution, as their commuter trains were already receiving low-voltage. While many commuter fleets were quickly converted to HEP, long-distance trains continued to operate with steam heat, five Amtrak E8s were rebuilt with HEP generators for this purpose

Air conditioning
–
Air conditioning is the process of removing heat from a confined space, thus cooling the air, and removing humidity. Air conditioning can be used in domestic and commercial environments. Air conditioners often use a fan to distribute the air to an occupied space such as a building or a car to improve thermal comfort. The cooling is achieved through a refrigeration cycle, but sometimes evaporation or free cooling is used. Air conditioning systems can also be based on desiccants and subterraneous pipes that can distribute the heated refrigerant to the ground for cooling. In the most general sense, air conditioning can refer to any form of technology that modifies the condition of air, in common usage, though, air conditioning refers to systems which cool air. In construction, a system of heating, ventilation, and air conditioning is referred to as heating, ventilation. Since prehistoric times, snow and ice were used for cooling, the business of harvesting ice during winter and storing for use in summer became popular towards the late 17th century. This practice was replaced by mechanical ice-making machines, the basic concept behind air conditioning is said to have been applied in ancient Egypt, where reeds were hung in windows and were moistened with trickling water. The evaporation of water cooled the air blowing through the window and this process also made the air more humid, which can be beneficial in a dry desert climate. In Ancient Rome, water from aqueducts was circulated through the walls of houses to cool them. Other techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the hot season. The 2nd-century Chinese inventor Ding Huan of the Han Dynasty invented a fan for air conditioning, with seven wheels 3 m in diameter. During the subsequent Song Dynasty, written sources mentioned the air conditioning rotary fan as even more widely used, in the 17th century, Cornelis Drebbel demonstrated Turning Summer into Winter for James I of England by adding salt to water. The introduction of air conditioning in the 1920s helped enable the great migration to the Sun Belt in the United States. In 1758, Benjamin Franklin and John Hadley, a professor at Cambridge University. Franklin and Hadley confirmed that evaporation of volatile liquids could be used to drive down the temperature of an object past the freezing point of water. They conducted their experiment with the bulb of a mercury thermometer as their object and they lowered the temperature of the thermometer bulb down to −14 °C while the ambient temperature was 18 °C

Opened in 2006, Berlin Hauptbahnhof is a large station at the crossing point of two major railways and features modern, abstract architecture. Berlin had a ring of terminus stations, similar to London and Paris, however they were gradually replaced with through stations from 1882 to 1952.

Broad Green station, Liverpool, shown in 1962, opened in 1830, is the oldest station site in the world still in use as a passenger station.

Opened in 1830 and reached through a tunnel, Liverpool's Crown Street railway station was the first ever railway terminus. The station was demolished after only six years, being replaced by Lime Street Station in the city centre. The tunnel still exists.
